. HAND-,PROPELLEVR F'pOR SMALL BOATS.

SPECIFICATION fOrming part of Letters Patent N0. 402,482, dated April 30, 1889.

Application-Med January 24, 1889. Serial No. 297,425. (No model.)

To all whom; it may concern: 4

Be it known that I, EDWIN W. SCHILD- KNECIIT, of Boston, in the county of Suolk and State of Massachusetts, have invented a new and useful Improvement in Hand-Propelling Attachments for Small Boats, of which the following is a specification.

This device is an attachment for small boats, adapted tobe readily removed from andV at tached to the stern, whereby they may be propelled by means of a crank in the hand of the occupant of the boat.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l is a vertical section of my device in position upon a boat, the stern of whichl is shown in lside elevation. Fig. 2 is a plan view of the same with the cover removed.

A represents a box provided with a swinging cover, A hinged at d to said box, whereby the mechanism within is kept from exposure to the weather.

B represents a portioirof the stern of a small boat provided with 'two or more eyebolts, b. The box A and a rod, F., (below de: scribed,) extending therefrom, are provided with pintles C, the vertical portions of which are adapted to drop into the eyebolts b. Thus the propelling attachment may be shipped and unshipped with' ease. The opposite side of the propelling attachment is provided-with eyebolts b', similar to the eyebolts b, and the rudder-post D is provided with pintles d, dropping into said eyebolt-s b. The post or shaft D of the rudder extends up to a point a little above the box A, and its upper end is squaredr to receive the tiller D, which extends horizontally at right angles with the rudder, so as not to interfere with the lifting of the cover A of the box A.

E is a rod bolted to the side of the box A next the boat and extending downward into the water, bent horizontally at E', as shown,

and vertically at E. A horizontal shaft, e,

has its bearings in the two portions E E of the said rod, and rigidly secured to this shaft are asprocket-wheel, F, and the paddle-wheel or propeller proper, I-I. Suitable collars, e', upon the shaft e keep the wheel and propeller in proper position.

Within the box A, and supported in bearings f therein, is a shaft, I, (shown by broken lines in Fig. 1,) rigidly secured to which are a sprocket-wheel, L, and a pinion, J. The sprocket-wheel' L is connected with the sprocket-wheel F by a chain, K. Below this shaft I is another shaft, N, supported in bearings g in the box A, to which shaft is rigidly secured the gear-wheel P, which engages the pinion J. One end of this shaft extends through the box toward the boat and is squared to receive the crank R. Suitable collars, h l, upon the shafts I and N hold the wheels thereupon in position.

The occupant of the boat, by turning the crank R, rotates the gear-wheel P, and hence the pinion J, shaft I, and sprocket-wheel L, which, by means of the chain K, rotate the sprocket-wheel F, shaft e, and paddle or propeller H, thus setting the boat in motion.

The rudder is easily operated by extending a hand over the box to the tiller D.

The propelling device may be readily re- Inoved from the boat by simply lifting it out of the eyebolts b, and the rudder may easily be unshipped from the propelling device and returned to its ordinary position upon the boat.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The herein-described improved propelling device for small boats, consisting, essentially, of the box A A and bent rod E E E, supporting the same andV provided with the pintles O and eyebolts b, the shaft e, supported by said bent rod and carrying the propeller Il and sprocketfwheel F, chain K, shaft I, supported within the box and provided vwith the sprocket-wheel L and pinionJ, and shaft N, supported by the box and provided with the gear-wheel P and crank R, substantially as and for the purpose set forth.
